This scatter plot visualizes automobile data from the auto-mpg dataset, plotting each car as a circle positioned by its horsepower and weight. The SVG rendering uses D3 v6 scales including `scaleLinear` for the x-axis and `scalePoint` for the y-axis, with axes generated by `axisBottom` and `axisLeft`. Circles are appended via data joins, and tick formatting converts large numbers using D3's `format` function, while styling is applied through external CSS classes.
